To all whom it may concern:

Be it known that I, FREDERIC C. SMITH, a citizen of the United States, residing at WVaterbury, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Vacuum- Bottles; and I do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this application, and represent in- Figure 1 a View in side elevation of a vacuum-bottle constructed in accordance with my invention, a portion of the coupling-ring being broken away.

Fig. 2 a broken view of the bottle with the inverted nest of cups and coupling-ring in vertical section.

Fig. 3 a detached view in side elevation of the coupling-ring.

Fig. 4 a corresponding view of one of the cups.

My invention relates to an improvement in vacuum bottles, the object being to provide such bottles with a nest of drinking cups which, when not in use, serve as a component part of the shell-structure to close the mouth of the bottle, whereby I provide in one self-contained tructure, a bottle and a plurality of drinking cups.

With these ends in view, my invention consists in a vacuum bottle provided with a nest of tapered drinking cups uniform in size and forming when not in use a part of its envelop or shell, and also in certain details of construction as will be hereinafter described and pointed out in the claims.

In carrying out my invention as herein shown, I employ a nest of three drinking cups 2 all of the same size and each provided with a concentric nesting-shoulder 3 and a concentric-offsetting rim 4, the shoulder 3 of one cup engaging with the inner face of the rim 4 of the adjacent cup, whereare regularly spaced apart as shown in Fig. 2, so that they are readily disassembled when required for use. The internal diameter of each cup at its open end is adapted in size to fit snugly over a centering-shoulder 6 which surrounds and rises above the neck of the bottle proper which is not shown, but understood to be a doublewalled glass bottle with the space between its walls exhausted to form a vacuum. The

ed flange 10 adapting the said cap to be screwed upon the correspondingly threaded upper end of the cylindrical sheet-metal shell-body 11 which is of ordinary construction. For securing the nest of cups 2 in place, I employ a coupling-ring 12 the lower portion of which is threaded as at 13 to adapt it to be screwed over the threaded collar 7 and formed upon its lower edge with a finishing bead 14. The upper edge of the ring 12 is drawn inward to form a grippingedge 15 inclosing a circular opening 16 just large enough in diameter to permit the cups to pass through it barring their rims 4. In other words, the opening 16 is a trifle larger in diameter than the nesting-shoulders 3 of the cups but smaller in diameter than the diameter of the rim of the cups. Now no matter in what order the cups 2 are nested, the edge 15 will always engage with the under face of the rim 4 of the outermost cup of the nest as shown in Fig. 2. The parts are proportioned so that when the nest of cups is inverted and centered upon the shoulder 6 and the coupling-ring 13 is slipped down over the cups and screwed home, the aid ring acting through its edge 14 and the rim 4 of the outermost cup, draws the nest of cups solidly down over the shoulder 6 until the uper face of the rim of the innermost cup rests upon the ledge 17 between the shoulder 6 and the collar 7, as shown in Fig. 2. When the cups are'nested and applied in the manner described, they form a component part of the shell-structure of the bottle, inasmuch as they actually house the neck and mouth of the bottle which is closed by a cork 18 of any suitable size and shape and character. On the other hand, when the coupling-ring 2 is unscrewed, the nest of cups are freed to be used as any cups are used. By making the several cups uniquiring the initial construction and maintenance of as many dies as there are cups. Furthermore, by making the cups of the same size, they may be quickly assembled in any order, whereas when graduated cups are used, they must be sorted over and systems atically arranged prior to being nested. Moreover, cups of uniform size are effective for closing the bottle-structure irrespective of their number, whereas, when difierentiated cups are employed, the bottle cannot be closed'without the presence of the largest cup, which thus becomes the master-cup, as it were, and is indispensable.

ll claim 1. As a new article of manufacture, a vacuum bottle having a shell, a nest of interchangeable tapered drinking cups applied as a nest to, the said shell so as to form a component part thereof, the said cups being uniform in size and each having a concentric ofisetting rim, and means engaging with the rim of the outermost cup and with the shell for positively securing the nest of cups thereto with the outer cupexposed and forming a tapering end for the-said shell of the bottle.

2. As a new article of manufacture, a vacuum bottle having a shell comprising a shell-body and a shell-cap removably applied thereto, a nest of interchangeable tapered drinking cups of uniform size adapted to be centeredas a nest in inverted position upon the said shell-cap and each having a concentric ofisetting rim, and a threaded menace coupling-ring adapted to be removably secured to the said shell-cap and to engage with the rim of the outermost cup of the nest of cups so as to hold the nest positively in place upon the said cap with the said outer cup exposed so as to form a tapering end for the shell.

3. As a new article of manufacture, 'a vacuum bottle having a shell comprising a shell-body and a shell-cap removably apphed thereto and formed with a centering-shoulder and a threaded collar, a nest/of interchangeable drinking cups adapted to be centered as a nest in inverted position by set ting the innermost cup over the said centering-shoulder, and a threading coupling-ring adapted to be engaged with the threaded collar of the said shell-cap and formed with a retaining-edge adapted to engage with the rim of the outermost cup of the nest of cups so as to 'hold the nest positively in place upon the said centering-shoulder with the said outer cup exposed so as to form a taper- 1n end for the shell of the bottle.

dn testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
